“The true, the genuine worship is when man, through his spirit, attains to friendship and intimacy with God. True and genuine worship is not to come to a certain place; it is not to go through a certain ritual or liturgy; it is not even to bring certain gifts. True worship is when the spirit, the immortal and invisible part of man, speaks to and meets with God, who is immortal and invisible.”
William Barclay was an author, radio and television presenter, Church of Scotland minister and Professor of Divinity and Biblical Criticism at the University of Glasgow.
While professor, he decided to dedicate his life to "making the best biblical scholarship available to the average reader". The eventual result was the Daily Study Bible, a set of 17 commentaries on the New Testament, published by Saint Andrew Press, the Church of Scotland's publishing house.
The 17 volumes of the set were all best-sellers and continue to be so to this day. Barclay wrote many other popular books, always drawing on scholarship but written in a highly accessible style.
